The combustion furnace adopts 3-layer thermal insulation, the inner furnace adopts high aluminum refractory ,anti-souring and high temperature resistance. Outside of the furnace, it uses water cooling system Multiple air increasing, high temperature pyrolysis, semi-gasification suspension combustion, heat convection and radiation together, combustion last for more than 2 seconds, high-speed combustion and no dead corner.

Q3

Why you use water cooling system, not air cooling to biomass burner?

If biomass burner connect with boiler, it is ok to use the cold water from water and the hot water back to boiler, in this way, it can save energy compared to fan cooling. The water pump is smaller than air fan and it can save electricity consumption. The cooling time will be more fast than you use the fan.

Q4

What about the ignition device, can I ignite biomass burner without this device?

It is diesel automatic ignitor for 5-8minutes, Brand BALTUR from Italy It is ok to ignite burner without this device, and we can use burning material instead of ignitor.

Q5

This biomass burner can work continuous or not?

Yes, 24hour/days is no problem. When we discharge ash, it is no need to turn off the burner, owing to the system is micro negative pressure operation, ensure no gas or fire leakage.

Q6

What is requirement for the raw material?

Moisture should be less than 15% Size: 6-8mm for pellet burner, 10*20mm for wood chips burner, 1-3mm for sawdust burner, 60-80mm for wood powder burner It will be better to use good raw material and remove impurity as much as we can.

Q7

What about the emission of biomass burner, does it pollute environment like coal boiler?

Ash<1~1.5%, flue gas emission<50mg/m3 Biomass burner use wood pellet, sawdust, wood powder or other agriculture waste, which are recyclable and environmental-friendly, not like the coal producing large amounts of waste and dust.

Q8

If we need your engineer to guide installation and operation for biomass burner, how long will be finished? What about the temperature of the frame?

Normally, 2-3 working days will be ok if all equipment are ready. The frame is about 900-1100degree.

Q9

How many people operate this biomass burner and what about the lifetime of your equipment?

The operation is simple and a single person on duty can finish the work. The buyer should operate the biomass burner according to the operation manual the seller supplied and 8-10year is no problem.

Q10

Can you make a brief introduction to compare your three type biomass burner?

Biomass pellet burner has the best price, owing to it has a hopper together with body. The pellet is easy for delivery and store. Biomass sawdust burner has an extra fuel bin, so the price is higher than pellet burner, but the sawdust has the lowest cost compared to pellet and wood powder. The efficiency is 90-95%. Biomass wood powder burner also need an extra fuel bin, but it has the best performance 95-98%.

1. What is the meaning of biomass gasification, is it a new technology?

Biomass gasification means incomplete combustion of biomass resulting in production of combustible gases, including Carbon monoxide (CO), Hydrogen (H2), Methane (CH4), CmHn, this mixture is called pyrolysis gas that can be used to run internal combustion engines, and generate CHP. Gasification is a century old technology, which flourished quite well before and during the second world war. Today, because of increased fuel prices and environmental concern, there is renewed interest in this century old technlogy. Gasification has become more modern and quite sophisticated technology.

Q2

Which material is suitable for biomass gasifier, can we also use city waste as fuel?

If the raw material is 1ton wood chips, we can get about 2500m3 syngas, 100kg carbon, 150-200kg wood tar.

Q6

6. Can we get more detail, 1ton/h wood chips gasifier, what is the output of gas, wood tar, what utilities are required, operational cost, electricity?

The output of gas is about 2500M3/h The wood tar is about 150-200KG/h The ash is about 100kg carton. Two workers will be needed for the operation. The electricity is 40.5KW each hour Water and tar(heavy oil) are together, so we can make about 5m*6m*3m pool to handle sewage, and get heavy oil from it. The chemical material will be needed to make water meet the requirement of environment requirement.

Q7

Can we use only plastic waste as fuel for gasification?

If it is difficult to find more biomass material, it is ok to use plastic waste as fuel for gasification, but the gasifier will need extra biomass material at the beginning, then put plastic waste inside gasifier furnace for gasification. To discharge ash automatically, we need to put extra biomass material before gasifier stop working.

Customize Content

The combustible gases from the gasifier can be used a) in internal combustion engines, b) for direct heat applications and c) as feedstock for production of chemicals like methanol. In order for the gas to be used for genset, it should be cleaned of tar and dust and be cooled.

Q2

How many of your power plants are in operation and where are they located on oversea market?

100KW wood chips gasification power plant in Congo, April 2014 200KW wood pellet gasification power plant in Russia, April 2014 500KW city waste gasification power plant in Thailand, March 2015

Q3

How many space needed for a 500KW power plant, and how many KWH can get each year?

60m*3m, not included sewage pool and water circulation pool. The sewage pool need to check the moisture of raw material, the water circulation pool need to check your local climate. Normally, we need to do maintenance each month and a full inspection once every three months. The power plant can work 300days, so we can get 3,600,000KWH each year.

Q4

How much water is required for the cooling pond to 500KW gasifier and gas cleaning system.

To the gasifier, need 4~5t circulation water for cooling To the purification system , need 7~10t circulation water for cooling To the generator, need 1~2t circulation water for cooling To the 500kw, the water consumption around 300kg/day

Q5

Can we use the waste heat from gasification system for house heating or hot water boiler? If yes, how many of the waste heat can be from 500KW power plant?

The heat waste is about 2000000Kcal/h from 500KW power plant, and we can use it for house heating or circulation with hot water boiler.

Q6

What about the emission from the power plant, do you have a test data?

What happens when the plant runs at a smaller capacity, or at a larger capacity?

When gas supply is insufficient, Gen sets will stop working, when gas supply is sufficient, because self-priming function of Gen sets, we can make a corresponding adjustment,to achieve continuous and stable operation .

Q8

For example: maximum biomass consumption per hour is 0.3~0.5 tons, how many Kwh will this produce and how much heat?

1kg wood chips can produce 2~3m3 syngas , 2.5m3 syngas can generate 1kw electricity. It means 0.3~0.5ton wood chips can produce around 300~500kw electricity, the whole system can get around 1000000kcal heat, can be used for room heating
